My invention relates to improvements in v a slidingvdoor construction, and it consists in the combinations, constructions and arrangements hereinafter described and claimed.

An object ofmy invention is to provide a-metal sliding door structure that can be manufactured and shipped in assembled .or in a knock down condition. y The device is primarily designed to be usedin buildings constructed of steel which are known as class A- buildings, and the samedevice can also be used in buildingsconstructed of wood known as class C buildings. The metalpart of the device is made narrow enoughto fit into walls four inches thick used in class A constructions. By the addition of filler strips .to the same metal structure, the device can be used inwalls live inches thick :employed in class structures.

f The steel frame for the sliding. door is so constructed as .to allow the nailing on of wall board or lath for holding plaster and also jainbs', casing and interior finish.

A further object of my invention is to provide a device. of the typedescribed in which the doorway of.- the completed structure is large enough tope'rmit the sliding door .to be removed through the doorway ,.it only being requiredto firstremove'the stops used in standard doorways. Also the door hangers can be removed without removing-the door or finish. f d Other. objects and advantages will appear as the specification proceeds, and the novel features of the device will be particularly pointed out in the'claims hereto annexed.

My invention is illustrated in the accompanying drawings, in-which: v Figure 1 is a perspective view of the assem- I Figure Qis aseotion along the line 22 shows the device used in class A construction, g

Figure 3 is a s ectional'ong the line 3-3 of Figure 2,

Figure 4 shows the device as used in class C construction. and is a section along the line 4+4 of Figure 5, f

by bracket-s 6 and 7.

Figure 5 is a section along the line 55 of Figure 4, p a p Figure 6 is a side elevation-of the form oi the device, shown in Figure 4, and t Figure 7 is ahorizontal section of a modi- 5| .tied form of the device.

In carrying out my invention, I provide a substantially all metalsliding door.constructionwhich comprises an end channel iron 1 that extends vertically, two supporting channel irons 2 and 3that form one part of a doorway, and an end channel iron 4. A horizontally-disposed channel iron 5 (see Figure 1) extends between the end channel irons 1 and 4 Iandis secured to the channel irons 55 The sides 8 of the channel iron 1 are cut away as at 9 for receiving thefchannel iron 5.

The channel irons 2 and 3 are disposed with their sides 10-10 outwardly. Rivets 12 secure the channel irons .2 and .3,to the sides 13 of the channel iron 5.

A rail-supporting channel iron 14 underlies the channel iron 5 and is secured to this channel iron by rivets 15 or other suitable fastening means. Figure 2 clearly shows how the channel iron 14 is disposed adjacent to one edge of the channel iron 5 and how the bottom of the channel iron 14 is disposed in a vertical plane. Brackets 16 (see Figure 2) secure the lower side 17 0f the channel iron .14 to the cndchannel irons 1 and 4. A railsupporting block 18,( see Figures 1 and?) extends along the length of the channel iron ;14 and is secured in place by bolts 19 or other suitable fastening means. 20 is carried by the block 18.

A wooden rail The structure thus far described is adapted for use in steel buildings or in buildings made of wood. It can, therefore, be manufactured in large uantities and shipped to the various types of buildings and be placed in position, after which the finishing material can besecured in place. Iwill first describe the ,device' when used in a steel building. I Figures 2 and 3 illustrate this type of structure.

In Figure 2 I show a small horizontallydlspose'd channel iron 21 extending from the and 11-11 facing lie channel iron 1 to the channeliron 2 (note Figure 1). This channel iron may be secured in place by any suitable fastening means. A second small channel iron 22 (see Figure 2) extends between the channel iron 1 and the channel iron 3 and is disposed in a lower position than the channel iron 21. The channel irons 21 and 22 form the top of the door opening and support wall boards 23, these boards being placed in the channels as shown and extending upwardly to the top of the frame. Side jambs 24 made of wood (see Figure 2) extend upwardly along the sides 10 of the channel irons 2 and 3. Figure 3 also shows this construction. The jambs are spaced from each other to provide a slot 25 through which a sliding door 26 moves. The other side of the door opening is provided with a side jamb 27 (see Figure 3) and this jamb is secured in place by nails (not'shown) that pass into a filler strip 28 disposed in the channel iron 1. All of the supporting channel irons 1 to 4 inclusive have perforations on their bottom and sides for receiving fastening means that secure fillers and jambs to the channels.

Theside jambs 2424 and 27 support top jambs 29 and 30. The jamb 30 is shown thicker in Figures 1 and 2 than the jamb 29. Figure 1 shows how the jamb 30 is formed in two pieces 30a and 30b and how these pieces are out on a bias as at 31 for permitting the piece 30?) to be removed when it is desired to gain access to the door hanger indicated generally at 32 (see Figure '2).

The particular construction of the door hanger is described and claimed in my copcnding application Serial No. 378,692, filed July 16, 1929. 'This hanger can be removed from the door when a locking member 33 is swung into inoperative position. Figure 2 shows how the member 33 can be reached when the block 305 is removed. The door can then be removed from the hangers 32. Of course, stops 34 are removed from the door jambs so as to provide a door opening large enough to permit the removal of the door.

It will furtherbe noted from Figures 1, 2 and 3 that the rail-supporting member 18 is provided with a cut-away portion 35 which permits the door hangers 32 to be removed from the device or to be inserted in place when desired. The space between the member 18 and the opposing wall is not suflicient for the passage of the hanger roller. The

cut-away portion or recess 35 provides room for the passage of the hanger. I have shown two hangers supporting the sliding door, although this number may be increased if desired. A wrench, not shown, can be used for engaging with a non-circular portion 32a ofa bolt 32?) used in the hanger 32. The turning of the bolt raises or lowers the door into the proper position.

I will now describe how the structure shown in Figure 1 is encased for class A building construction. The channel irons 2 and 3 (see Figure 3) are provided with filler strips 36 and 37, and the door casing members 38 are secured to the filler strip. The portion of the structure disposed above the small channel irons 21 and 22 is enclosed by the wall board 23 (see Figures 2 and 3). Plaster 39 covers the wall board.

The sliding door pocket defined by the channel irons 2, 3 and 4 is covered by a wall board 40 (see Figure 3) that is removably secured in small vertically-disposed channel irons 41 and is secured to the channel iron 4 by special wire fastenings shown in my copending application filed October 23, 1929, Serial No. 401,890, or nailed to extended filler strips or studs. These channel irons are secured to the sides 10 and 11 of the channel irons 2 and 3. In case the distance between the channel irons 2 or 3 and the channel iron 4 is great, double channel irons 42 and 43 are used for receiving the ends of adjacent wall boards 40. Plaster 44 is applied to the wall boards 40 and forms a continuation of the wall of the room.

' As already stated, the same device shown in Figure 1 is used in class C buildings except that the small channel irons 21 and 22 are dispensed with. The wood type structure is shown in Figures 4, 5, 6 and 7, and like parts will be given like reference numerals without the need of any further description. The material covering the structure shown in Figure 1 difiers from that shown in Figure 3 and provides a thicker wall which is used in class C structures. Above the top jambs 29 and 30 I dispose sheathing 45 which rests upon the top jambs 29 .and 30. This sheathing is shown in Figure 6, and is provided with horizontally-disposed grooves for receiving plaster. Lath 46 is secured to the outer surface of the sheathing, and the plaster 47 is applied to the lath.

- The sliding door pocket is covered by sheathing indicated generally at 48. Figure 4 shows how a filler member 49 is secured to the filler strip 36 and how a second filler member 50 is secured to the filler strip 37. Before the filler strips 49 and 50 are secured in place, they are mounted in a form, and the diagonal sheathing 48 is secured to the members by nails 51 or other suitable fastening means. The sheathing as a unit is then disposed on the out-side of the pocket .and the filler members 49 and 50 are secured to the filler strips 36 and 37. Lath 52 (see Figures 5 and 6) is then disposed on sheathing, and this is covered by plaster 53. The sheathing is also secured to a stud 54 that is connected to a filler strip 55 disposed in the channel iron 4.

' The'top jamb 30 shown in Figure 6 is in two pieces 30a and 3012 as alread described, and these pieces are removab y held tomatter gether by screws 56'. The piece 306. is re moved when it is desired to releasethe hangers from the door2'6. A door spring 57 is shown in Figure 11. Small blocks 58 are disposed between the'sheathing 18" and the lath 52 is secured'to the blocks.

l In Figure 7 I show another modified form of the invention in which verticalchannel irons 100'and101 are disposedbetween the channel'irons 2 and 3 and thechannel iron 4. The purpose of the additional channel irons 100 and 101 is to support lath 102 or wall board that is secured to filler strips 103 mounted on the channel irons 100 and 101. Screws or other fastening means are passed through the bottoms of thef channel irons 100 and 101 and securethe filler strips 103 in place. Nails (not shown) secure the lath 102 or wall board to the filler strips 103.

The lath is also secured to the filler strips 36 and 37 disposed in the channel irons 2 and r e 3 and to a stud 104 disposed adjacent tothe channel iron 4:. Plaster 105 is applied to the V lath 102.

The channel irons 2 and 3 have openings in their bottoms for receiving screws or oth er fastening means which secure the filler strips 36 and 37 to the channel irons. Side jambs 106 are secured to the filler strips 36 and 37 by nails or other suitable fastening means that pass through the jambs and on through openings in the sides 10 of the channel irons 2 and 3. Grounds 107 are secured to the filler strips 36 and 37 by nails or the like, and stops 31 are secured to the jambs 106. The lath or wall board is secured to the filler strips 36 and 37 and is abutted against the grounds 107. The plaster 105 is applied to the lath 102 and is made flush with the outer surface of the grounds 107. The door casing 38 is now secured to the grounds 107 and jambs and extends over a portion of the plaster. The door jambs 106 and stops 3 1 disposed adjacent to the pocket B have a slot 108 cut therein for receiving the sliding door 26.

In all other respects this form of the device is identical to the other forms and needs no further description.
